-* Renesas R-Car GPIO Controller
-
-Required Properties:
-
- - compatible: should be one of the following.
- - "renesas,gpio-r8a7778": for R8A7778 (R-Mobile M1) compatible GPIO controller.
- - "renesas,gpio-r8a7779": for R8A7779 (R-Car H1) compatible GPIO controller.
- - "renesas,gpio-r8a7790": for R8A7790 (R-Car H2) compatible GPIO controller.
- - "renesas,gpio-rcar": for generic R-Car GPIO controller.
-
- - reg: Base address and length of each memory resource used by the GPIO
- controller hardware module.
-
- - interrupt-parent: phandle of the parent interrupt controller.
- - interrupts: Interrupt specifier for the controllers interrupt.
-
- - gpio-controller: Marks the device node as a gpio controller.
- - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
- cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
- GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
- - gpio-ranges: Range of pins managed by the GPIO controller.
-
-Please refer to gpio.txt in this directory for details of gpio-ranges property
-and the common GPIO bindings used by client devices.
